As I said above, the Census forms have no bearing on the problem you raised in your first post, and the image you have just supplied. So we need to exclude those completely from this topic.
So, returning to the original issue, have you done as I suggested and re-enabled all the modules you use, and saved their access configurations? That image, and a quick look at your site, suggests not.
If you have done those things, then you will need to find an error message somewhere on your server to give me a clue as to what is happening.
